    摘要： A process for the production of primary and/or secondary amines from imines or nitriles, comprising an aminating hydrogenation of imine or of nitrile with hydrogen in the presence of ammonia, of a hydrogenation catalyst based on cobalt, nickel, ruthenium or mixtures of these metals and of a base, at a temperature within the range of 50.degree. C. to 200.degree. C. and at a pressure within the range of 0.3 to 30 MPa. The yield of amine is increased by the use of a quaternary ammonium hydroxide as base. Preferably a tetraalkylammonium hydroxide is used in a quantity of from 0.01 to 100 mMol per mol of amine or of nitrile. The process is suitable in particular for the production of isophoronediamine from isophorone nitrile imine.

    摘要： An improved process for reducing aromatic nitro compounds to form the corresponding aromatic amine compounds, and intermediates therefore, and a reducing agent therefor, are disclosed. According to the process, a titanium(IV)oxy salt such as titanium(IV) oxysulfate is electrochemically reduced to form a titanium(III)oxy reducing agent, which can be employed to chemically reduce the aromatic nitro compounds, and the resulting re-oxidized titanium salts may be recycled to the electrochemical reduction step of the process. The titanium(III)oxy salt product is highly soluble in strong acid solutions and exhibits improved oxidation stability.
